Abstract: A kitchen fume-cleaning apparatus is provided. The kitchen fume-cleaning apparatus includes a main body having a receiving space therein, in which the main body includes an air inlet mounted on one end thereof and an air outlet mounted on the other end thereof. The air inlet, the receiving space, and the air outlet are configured to communicate with each other. The air inlet is set to allow an exhaust fume to enter the receiving space therethrough. A filter device and a sterilization device are mounted in the receiving space for degreasing, deodorizing, and purifying the fume. Thus, the gas expelled through the air outlet is a clean and non-polluting gas.
